Bordetella pertussis culture
Bordatella pertussis is the causative agent of whooping cough. The disease is characterised by a mild respiratory infection following a 7-10 days incubation period. The cough changes character after 1-2 weeks and becomes more paroxysmal followed by an inspiratory "whooping" sound. The cough ultimately subsides after 1-2 months.
